vhaudiquet 3618d9857e ci: build the snap and run an apt e2e against it
The snap only got built at tag time, so the pack rotted between
releases; ci now packs it on every change, the same action the
release workflow uses, and boots it twice: an alpine uname check
that proves the machine virtualized under strict confinement, and
apt update + install fastfetch on ubuntu, which is T8 — a real
package install through the TSI proxy, the staged e2fsprogs, and
the exit-code path, with the wall time as the standing
re-measurement of the ln driver's throughput.

ecrou

a small microVM runtime based on libkrun

Try ecrou in the terminal

Installation

ecrou is available as a strictly confined snap:

sudo snap install ecrou
sudo snap connect ecrou:kvm

Usage

$ ecrou run -it ubuntu
root@ecrou-vm-m2glhl:/# 

Embed ecrou into your project

ecrou is both a library and a tiny CLI frontend around it. The library is embeddable into any project, allowing to use microVMs easily.

Rust

ecrou is a Rust library, which can just be called:

use ecrou::vm::RunOptions;
use ecrou::NoProgress;

fn main() -> ecrou::Result<std::process::ExitCode> {
    let code = ecrou::vm::run(
        &RunOptions {
            image: "ubuntu:resolute".into(),
            command: vec!["uname".into(), "-a".into()],
            ..RunOptions::default()
        },
        &NoProgress,
    )?;
    Ok(std::process::ExitCode::from(code.clamp(0, 255) as u8))
}
